Applications of flooring adhesive
Supex Flooring Adhesive is suitable for paving and pasting indoor wall panels and floors. It is suitable for various paving methods. It is especially convenient for the full-paving construction. It has a good heat transfer effect for wooden floor full-paving systems with a geothermal system at the bottom.
How to use
- In order to ensure the adhesion, the surface of the paved ground must be hardened, loose ground will affect the adhesion.
- For long or wide floors or uneven ground, try to install and flatten the floors first and then use the adhesive, and flatten the floors again after
- The pot life of the adhesive is related to the environmental temperature and humidity, and it is easy to form skin under high temperature and high humidity environment and shorten the operation
- Suitable for using at +5 ℃ ~+40 ℃ , recommended temperature and humidity: +10~+30 ℃ , 30%RH~80%RH.
- Due to the differences of floors and woods, it is recommended to test the adhesion before using.
